Foundation support



May 26, 1959 E. w. CHINN FOUNDATION SUPPORT Filed Dec. 5, 1952 INVENTOR-ERLE w.cH//v- ATTORNEY nited States This invention relates to new anduseful improvements in foundation supports for structures and being ofsuch construction and having means to prevent termites and other insectsfrom reaching the structure above the foundation supports.

An object of the invention is to provide foundation supports made ofpermeable materials such as concrete and the like, however said supportsmay be made of any material or construction which may be of a permeablecharacter as a mass to permit a liquid or insecticide solution topermeate from the chamber or cavity in said supports to the exteriorsurfaces of said supports to act as an insect repellant to preventinsects from ascending to the building or structure thereabove and fromdamaging the same.

Another object of the invention is to provide foundation supports of thecharacter described either in separate piers or in chain wallconstructions.

A further object of the invention is to provide foundation supports ofthe character described which are of very simple and cheap constructionand can be used safely in building construction to avoid fire hazardsand yet maintain symmetry in the foundation for buildings andstructures.

A still further object of the invention is to provide a method ofcoating the exterior surfaces of a mass, for example, a permeablefoundation support of concrete or the like, whereby liquids may beintroduced into said mass and causing the same to permeate constantlythrough the mass to keep the exterior surfaces of the mass coated withthe liquids at all times.

These and other objects will in part be obvious and will in part be morefully disclosed in the specification, the drawings of which show by wayof illustration one embodiment of the invention, in which The figure isa view in elevation of a foundation support with wood sill thereabovecovering the chamber or cavity therein.

Referring to the accompanying drawing in which like numerals denote likeparts in the various views, the foundation support or block 1 is shownto be made of concrete in the present embodiment of the invention,however, it is understood that it may be made of any material, mass orconstruction which permits of permeability suitable for the use hereintended. A chamber or cavity 2 is formed in the support or block 1,preferably with a slight taper extending downwardly from the top of saidsupport to within approximately the same distance from the bottom of thesupport as the distance from the sides of said chamber or cavity is fromthe side walls exteriorly of said support or block. The top 3 of saidchamber Patented May 26, 1959 or cavity is capped and/ or sealed offwith a sill or other cross support used in building construction or thelike as shown in the drawing. A port or trough such as indicated at 4leads from the exterior of said support 1 and communicates with thechamber or cavity 2 near its upper end through which liquids such ascommon known insecticides may be introduced therethrough to said chamberor cavity 2, a liquid fluid being shown at 5. A plug 7 is provided ofthe same configuration as the port or trough to prevent debris fromstopping up the port, and particularly, for sealing off the liquids inthe cavity 2 which may be introduced therein under pressure orotherwise.

The foundation support may be treated under pressure with fluids orpainted or soaked to insure initial coating on its exterior surfacesbefore installing as the foundation for a building or structure.Thereafter the chamber or cavity is filled with the liquids orinsecticide which will insure constant coating on the exterior surfacesof the foundation support or block by permeating through the same andmay be replenished when needed in convenient manner through the port ortrough which communicates with the chamber or cavity of the support.Crawling insects, such as the well known termites, will be discouragedfrom ascending the support as treated to the upper structure of thebuilding which has been found not only invading wood structures but frommasonry and thence to the wood structure thereabove in buildings whichhave done untold damage. The simple support as treated in this inventionwill positively and effectively eradicate this menace in a safe andeconomical way. I would prefer to use well known high penetratingliquids which are non-inflammable to eliminate fire hazards, many ofwhich are well known, thus providing fire proof foundation supports forall buildings or structures where used.

It is obvious that many changes in detail of construction may be madewithout departing from the scope of the invention as set forth in theappended claim.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent is:

A concrete foundation support for structures having a central chamberformed therein for storage of an insect repellant liquid, insectrepellant liquid in said chamber, said support being of a permeable masswhereby the liquid from said chamber will permeate through said supportto the exterior surfaces thereof, liquid from said chamber constantlypermeating through said support to constantly coat the exterior surfacesthereof, a port communicating with said chamber whereby an insectrepellant liquid may be introduced into said chamber, and means forsealing the upper portion of said chamber.
